In the paragraph following equation (8.17), the text states that there are no zeros if either the <math>B</math> or <math>C</math> matrix is "full rank".  This wording is misleading since a non-square matrix can be full rank without having fully independent rows (for <math>B</math>) or columns (for <math>C</math>).  The text should read
<blockquote>
Notice in particular that if the matrix <math>B</math> has full <font color=blue>row</font> rank, then the matrix
in equation (8.17) has <math>n</math> linearly independent rows for all values of <math>s</math>.  Similarly there are <math>n</math> linearly independent columns if the matrix <math>C</math> has full <font color=blue>column</font> rank. This implies that systems where the matrix <math>B</math> or <math>C</math> is <font color=blue>square and</font> full rank do not have zeros. In particular it means that a system has no zeros if it is fully actuated\index{fully actuated systems} (each state can be controlled independently) or if the full state is measured.
